How to add a public cloud network physical host to VPC

Abstract

The invention relates to the field of cloud computing and computer network, and specifically provides a method for a public cloud network physical host to join a VPC. The method connects the physical host to a ToR switch through a vlan, and the ToR of the physical host supports vxlan and multicast, and extends neutron Add the plugin and agent of the l2 gateway in the neutron server and expand the function of the generic network switch plugin, and configure the vlan and vni mapping of the ToR switch where the physical host is located, and add the agent extension of the l2 gateway in the openvswitch agent , the user manages virtual bridges and ovs flow tables. Compared with the prior art, the physical host and the virtual machine in the VPC can use the VPC intranet address to realize Layer 2 and Layer 3 interworking, realize the unified management of the virtual machine and the physical host, and have good promotion value.

technical field

[0001] The invention relates to the fields of cloud computing and computer networks, and specifically provides a method for a public cloud network physical host to join a VPC. Background technique

[0002] Openstack, as a mainstream product of open source Iaas cloud computing, has received widespread attention and general welcome from the industry, especially in recent years, the Openstack open source community and the commercialization of Openstack related products have achieved rapid development, but Openstack has As a public cloud IaaS platform operating system, there are still many functions to be expanded, such as supporting physical hosts to join VPC.

[0003] When Openstack is used as the public cloud Iaas platform operating system, in order to ensure the robustness and performance of network L3 traffic, it usually turns on the dvr (distributed virtual routing) mode in its network component neutron. In the dvr mode, the virtual router exists on the co...
